The side length of the square formed by joining mid points of the sides of ABCD is; 9√2
We are given;
Side length of square ABCD = 18 Inches
The midpoints of ABCD are joined to form a square abcd
To find the side length of abcd;
Since a,b,c,d are midpoints of ABCD, then;
ab = bc = cd = ad
We will use Pythagorean theorem to get; ab, bc, cd and ad.
Thus;
ab = √(9² + 9²)
ab = 9√2
